LOCK.

Application filed July 28`1 1927. Serial No. 209,057.

This invention relates to locks and pertains vmore particularly to a lock of the tumbler type adapted to be used for the locking of the operating mechanism of a vending machine and whereby a specially designed slug key, which takes the place of the ordinary coin now commonly used for this purpose, is utilized for the unlocking of the operating been operated the slug key drops from the. lock and is deposited into a receptacle to which vonly the proprietor of the machineY has'access. y

The object of the. invention is to provide a lock ofthe character above recited which will be highly eiiicient in operation, simple and durable of structure and which will be diflicult vof manipulation by any person other than one in possession of the -requisite key sl'ug. y

The above recited andother objects of the invention will be more fullyA described in the following specification and will be eX- emplied in the which v Figure 1 is a frontview of a casing embodying the invention parts being broken `j away and shown 1n section in order to more fully disclose the working parts.

\ In carrying out the invention a casing 1 0 is provided which may either be a. separate unit or form a part of the wall of a. vendaccompanying drawings, in

ing machine ("not shown) in which the mechanism to be operated by the lock-is. enclosed.

rlhe casing 10 c omprises a front plate 11 screw 13 and other vscrew 14:'. The plate 11 Ahas formed in it an annularchamber 15, and e the plate 12 is provided with an annu-lar cenv mechanism and after said mechanism has trally disposed boss. 16 which projects into the chamber 15 'and also with. an annular flange 17 at its periphery which also projects into the chamber 15, `thus forming an annular groove 18v in which is mounted fory rotation a ring 19.

lMounted forv rotation in ,chamber 15 is an annular disc 2O which is disposed between surfaces of the boss 16' and flange 17.

A pin 21 .is secured to thering 19 and projects. through a segmental slot 22 in the back plate 12 and has pivot'ed to it a link 23 adapted to forma connection with the slot machine lmechanism (not shown) to operate the same to perform any desired function.v j

An operatingjhandle 24: is secured to the disc 26 andv projects'through .a segmental slot 25 formed in plate 11, which alsohas formed in it, a slotl 26 for the admissionof a slug key 27.` F ormed in the back plate 12 is a slot 28 through which the key slug 27 is` ejected.

The ring 19 is made up of several pieces, for the purpose of conveniently machining the same, suitably secured together to form Y an annular pocket 29 therein, the opposite side Walls of which areprovided respectively with annular ribs 30 and `annular groovesA 31 to correspondwith ribs and depressions indicated at 31 on the key slug 27', and an the pocket 29 and in which an annular rib 33 secured to the disc 20 projectsya'nd said rib is provided on its vinwardly projecting surface with a notch 34 to receive the key slug 27, said slug being placed' between the edges 35 and 36 ofthe notch.

The ring 19 is providedwith yan aperture 37 iny its front wall adapted to register withl `the inner surface of plate 11 and the inner annular slot '32 which communicates with ers of group 40 pointing outwardly as shownV in Figure l of the drawings.

Plunger group 38 comprises the individual i plungers 41, 42 and 43, the plungerl 41 being of a certain diameter, the plunger 42 of a larger diameter` and plunger 43 of a still larger diameter and said plungers c are mounted to reciprocate in corresponding -sockets in the casing 10 and are pressed iiiwardly by means of springs 44. y

Disposed in front of .the plungers are tumblers 45, 46, and 47 of corresponding diaineters which at certain intervals during the operation of the lock are disposed insockets indicated at 48 and 49 formed in ring 19.

vThe key slug 2T is provided on its outer edge with indcnts 5() and cam surfaces 51 and on its inner edge witlriiidents 52 and cani surfaces 53.

Mounted in sockets formed inthe ring 19" similar to those indicated at 48 and 49-and disposed forward of tumbler 47 is a pusher tumbler 54 of greater diameter than tumbler 47, adapted toy ride along the inner peripheral surface of the annular groove 18.

Plunger group 39 comprises the individual y spring pressed pistons 55, 56, 57 and 58 mounted in suitable bores formed in the casing 10 said bores communicating with bores 59, 60 6i, 62 wliichare of increasing diameters and are adapted to receive the respective tumblers 45, 46, 47 v,and 54 during a transferring operation.

Plunger group comprises the individual plungers 63 and 64 and corresponding tumblers adapted to engagel .with the concaved edgev of the key plug 27and to operate in identically the same manner as plungers of group 38. l

Another group of spring pressed pistons indicated at'65 adapted to press outwardly but in other respects constructed similar to the group 39 is provided, and the bores in the casing` 10 operating` with the group are adapted to receive thel tuinblers of group 40. The mechanism constituting groups 40 and 65 could be dispensed with astliey merely serve to forni a certain combination and it is vobvious that the arrangement of all of the tuinblers may be varied to foi'mfa different combination.

l/Vhen the mechanism is in its initial. position,y the aperture 37m ring 19 is in register with the aperture 26 in casing 10 and the notch 34 is also in register with these apertures and the plungers of groups 38 and 40 slug and the tuniblers then drop into position into the indents 50 and 52 in the key, and the push tumbler 54 is engaged by the forward cani surface. f

Upon continued movement of the handle ing bores in groups 89 and 65l and consequentlyupon a continued movement of the? handle the cam surfaces ony the key slugact to push tl e tumblers into these bores. Continued movement of the handle pushes the keyinto register with the slot 28 throughk v which it drops by force of gravity, the casing being disposed on a slant to facilitate this action.

As the key passes from engagement with the tumblers they are forced into their Avra-y rious sockets in the ring, whereupon the ring carrying the tumblers will b e returned to its initial position by means of the. spring 66 which is secured to the lever 21 and casing properly calibrated key.
